Because you believe in the crypto currency idea, you – at some stage – had faith in Fedoracoin. They hope that by exchanging your dead coin for Rimbit, your faith will also move over to Rimbit. Users are the most valuable asset to any crypto currency and its community, and it would be a shame if you were to lose interest in the crypto currency idea because of a poorly developed coin, when there are viable alternatives like Rimbit.
You should get in touch with them by posting at their forum: http://rimbitforum.com.
I don't see Fedora listed anywhere on that site. Please explain how this works.
